Medical device maker Boston Scientific Corp. said Thursday a Canadian court dismissed a patent infringement lawsuit filed against the company by rival Johnson & Johnson.
New Brunswick, N.J.-based Johnson & Johnson sued Natick, Mass.-based Boston Scientific, claiming its NIR stents infringed two of Johnson & Johnson's patents. The court ruled that one Johnson & Johnson patent was not infringed and the other patent was invalid.
Johnson & Johnson is also suing Boston Scientific over its Express and Taxus Express stents.
Stents are tiny, mesh-wire tubes that prop open arteries after they have been surgically cleared of fatty plaque.
Johnson & Johnson could not immediately be reached for comment late Thursday.
Shares of Boston Scientific rose 26 cents to close at $13.68.
Shares of Johnson & Johnson fell a penny to close at $66.90.
